Low Ball Charge, Coarse Grind - Grinding Classification ...

The main ways to increase the power draw from a ball mill are to increase the level in the mill (add balls) or to increase the mill speed (can be done either with a variable speed drive or by changing the mill pinion to one with a different number of teeth). Checking Bond's ball size equation suggests the 100 mm ball is too coarse.
